Mustafa you will need to furnish a lot more information about what you want the smaller boat to do. How many people, how much gear and supplies like water, food, nav gear and all that kind of thing.............Is this to be a life boat, will it need a canopy like the cabin on the bigger boat????

Must the configuration of the smaller boat be proportionate to the larger one. If so it will not work. Not even close. The proportion is 3.0/6.5 =46%.....No way that 46 percent of 5900 kg....or 2720 kg can be supported by a tiny little 3 meter boat.

Be more specific. What is the purpose of the little boat?

I do not need a nice chess set, I already have one that I like very much, but thank you for the offer of your generous reward.

Messabout , I like the massive designs and 3 meters long boat will be my summer winter home - houseboat at Aegean Coast. I am extremelly determined to make it and it will be 150 cms high , 100 cms wide and 300 cms long.

Lets cut the corner. I attached an 27 people - same 6.5 meters long lifeboat design - and I want hull to be converted in to dwg line drawings. I need it because I will order laser cut plywood sections and than cover with 2500 grams glass roving and 3000 grams of polyester per square meters. I have 100 different boat plans but this is the best. I have autocad 2017 and finished 2d and 3d courses and I can draw upper structure.

@mustafaumu sarac I think I have understood that all you need is to translate the Rhino model to AutoCAD. Subsequently, your experience with this program will allow you to make the transformations you want. Accordingly, I have prepared these two versions of your boat, model with splines and model with surfaces, bot AutoCAD files. I hope some of them will be useful.

It is worse than that....as you've done your maths incorrectly.

The scale is correct 0.46....but when scaling a hull from one size to another, it is the cube of the scale.
Thus 0.46^3 = 0.097 x 5900 = 574 kg!!
Not a lot, if everything else remains the same...and of course the all important VCG scales the same ratio of 0.46 for this design to work as the original too.

Understand that you are almost surely on a fools mission if you insist on a boat such as the one you have in mind. . It is clear that you do not have much, if any, experience at sea.

The dimensions that you have specified will get you drowned, quickly if not sooner. A boat of the size that you describe might be satisfactory for a calm lake. It is not even close to being adequate for use in The Aegean sea. One meter wide, three meters long, and one and a half meters tall is going to require a lot of ballast in order to ...maybe...keep it upright if used in a seaway. The needed amount of ballast will require that the boat can not be designed according to your dimensions.

Even if we could make the boat as you wish, it is going to be painfully slow. That means that you can not hope to run from a storm. It means that your top speed will not be more than about 6km per hour even in the best of conditions. That means that if you decide to sail to Crete or Lesbos, or Cyprus it is going to be a very long trip when you will probably run out of water, food, and sanity before you get to the destination.

Please consider a boat of more practical dimensions for what you want to do. I/we would like you to survive as a forum member, not be lost at sea with an obscenely inadequate boat.

He can't iterate it for fear of reprisal or to lose the respect of forum members. He has very little operational financing. He wants to build a cheap boat that can move fast enough to evade capture and is safe enough to make some near shore crossing to greener pastures.

Before, the mo was a small boat he might self finance and now it is a collective project it seems.
